|Configuring data collection and expiration / Controlling data collection|
Performance data stored in OpsCenter expires after configurable time periods.
The default values are designed to provide efficient compaction and eventual deletion of the data, with faster expiration times for the more granular, larger-volume data rollups.
To change expiration time period:
In this example, the one-minute and five-minute rollups are set to expire twice as fast as the defaults, and two-hour rollups are set to be kept indefinitely (expiration is disabled).
